* fix: region() functions work for entities, having model, which is instantiated multiple times in a scene
* warn on Map_RegionBrush with none selected
* fix: 'region set brush' is deleting ultimateselected only (is using one to get bounds)
* deselect components on any region() function: could be texturized or edited implicitly
* allow 'region set selection' in components mode
* Map_RegionXY: deselect anything (could leave stuff selected + invisible)
* brush format is preference for [maptypes, brushtypes]: [mapq1, quake], [mapq2, quake2], [mapq3, quake3]:
preferences->Brush->Brush type: Axial projection, Brush primitives, Valve 220
* autodetect brush type on map opening
* brush face surfaceflags are optional on loading for flexibility
* 'Snap planes to integer grid' option is always off by default
misc...
* entity inspector, entity list->'autofocus on selection' buttons: also do FocusAllViews() on clicking them
* focus on preferences treeview on 2nd+ call to make text search to work
* fixed WindowPositionTracker globally: minus many particular hacks, plus correct wnds positioning in Floating viewports layout
* fixed ToggleShown functionality: shown/hidden wnds states are saved and loaded correctly in Floating viewports layout
* also save/load XY and Cam viewports visibility states
* new preferences->layout icons
* fix: stop chaseMouseMotion on mouse button release
misc...
* selection system: fixes of: selecting point behind point (not perfectly precise distance)
selecting occluded objects and faces via direct and indirect hits
* select models from back in 2d
binds...
* shift + m3: apply texture name and alignment to selected primitives and faces (m3 was inconsistent + often required quite deep planning)
* ctrl + shift + m3: also project tex from face to selection
misc...
* lazy cursor updates in clipper mode
* update cursor immediately on clipper mode toggles
* fixes and optimizations of entity names rendering; for instance: don't prerender textures for unneeded names
FBO overlay fixes
misc...
* render scene to FBO to get following options:
preferences->camera->MSAA (def = 8 samples)
preferences->orthographic->MSAA (def = 8 samples)
coloured camera POV icon w/o rerendering the scene
coloured rectangular selector box w/o rerendering the scene
* fallback to glCopyTexImage2D (NPoT), if FBO isn't available
misc...
* place created simple patch mesh not in middle of bbox, but on edge to make result more usable
* prefs-interface-layout-single scrollable toolbar
misc...
* changed surface inspector behavior from 'set whole texture projection' to 'set modified value' (makes sense for multiple surfaces selected)
* BP: surface inspector and Tex* binds scale texture by its axes, not world axes
* BP: fix rotation of tex projection with scale S != scale T
* BP: fix ruining nonregular tex projections by surface inspector (for example after fit/seamless/arbitrary projection)
* jump over tex projection scale = 0 case, while modifying one (AP and BP)
misc...
* restrict unwanted angle(s) keys commits on moving generic, eclassmodel, miscmodel entities
* reverted angle(s), origin, scale entity keys save format from %f to %g
* fix uniform rotation operations for generic entities with angles key
* use more precise meth for rotating point entities with only angle rotated
* snap tiny inaccuracies in angle(s) and origin point entities keys
* workaround: don't discard empty group ents, having origin key
* entity class convertion: prevent converting worldspawn; prevent converting point entity to empty group
menus...
* view->show->Entity boxes (always show bbox for ents with model)
misc...
FBO support
* preferences->display->entities->Names Display Ratio (2D): hide names, if view_size/bbox_size > value; def = 64
